Magnolia plant named &#39;JURmag1&#39;

ABSTRACT

A new and distinct cultivar of Magnolia named ‘Black Tulip’ characterized by flowering as a very young plant; flowering for long period; dark plum flower color; and the flower held upright on the tree.

[0001] Latin Name of the Genus and Species of the Plant Claimed:

[0002]Magnolia soulangeana

[0003] Variety Denomination:

[0004] Black Tulip

BACKGROUND OF THE INVENTION

[0005] The present invention relates to a new and distinct cultivar of Magnolia soulangeana referred to by the variety denomination ‘Black Tulip’.

[0006] The new cultivar was isolated by the inventor, Mark C. Jury, at North Taranaki in New Zealand, by seedling selection following controlled pollination of the maternal parent Magnolia ‘Vulcan’ (unpatented) with the paternal parent Magnolia ‘lolanthe’ (unpatented). The cross was made in 1986. The new cultivar was selected from the progeny of the stated cross by the inventor with the selection being primarily on the basis of flower color and form.

[0007] Following selection of the seedling, the cultivar was propagated from vegetative cuttings. Following several generations of propagated cuttings, uniformity and stability of the selected characteristics was observed. Horticultural examination of the present cultivar has demonstrated that the 20 combination of characteristics herein disclosed for Magnolia ‘Black Tulip’ are firmly fixed and are retained through successive generations of asexual reproduction.

[0008] The following table of characteristics indicates the manner in which the new cultivar is distinct from both Magnolia ‘lolanthe’ and Magnolia ‘Vulcan’. The comparison cultivar, Magnolia ‘Liliflora Nigra’, and Magnolia ‘Vulcan’ are the closest cultivars known to the applicant, but are quite different as shown in Table 1.

BRIEF DESCRIPTION OF THE INVENTION

[0010] The following traits have been repeatedly observed and are determined to be basic characteristics of Magnolia ‘Black Tulip’, which in combination distinguish this Magnolia hybrid as a new and distinct cultivar:

[0011] 1. flowering as a very young plant;

[0012] 2. flowering for long period;

[0013] 3. dark plum flower color; and

[0014] 4. flower held upright on the tree.

[0015] The following observations, measurements, and values describe the new cultivar as grown in Silvan, Australia under conditions which approximate those generally used in commercial practice.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The accompanying color photographs show the unique characteristics of the new cultivar of Magnolia ‘Black Tulip’, with colors as accurate as is possible with color photographs. The plants depicted in these photographic drawings are 3 years old. The first photographic drawing is a top view of a flowering ‘Black Tulip’ stem. The second photographic drawing is a side view of a flowering ‘Black Tulip’ stem with a bud. The third photographic drawing shows an individual ‘Black Tulip’ flower. The fourth photographic drawing shows a side by side comparison of a ‘Vulcan’ flower and a ‘Black Tulip’ flower.

DETAILED BOTANICAL DESCRIPTION

[0017] Color references are made to The Royal Horticultural Society Colour Chart (RHS) except where general colors of ordinary significance are used. Colors are approximate as color depends on horticultural practices such as light level and fertilization rate among other things.
